To @ZZ whom, t may concern:

Be itknewn that I, BIRNEY c. BATCHEL'LER,

a citizen of the United States of America,ree I siding in the city and county of Philadelphia,

in the State of Pennsylvania, have invented a certain new and useful Improvement in Flaming-Machines, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereo A My invention relates to the construction of planing-machines adapted to operate on concave cylindrical surfaces, and particularly for planing the concave'cylindric'al faces of annular rings-such as are used, for instance,

in my receiving and transmitting apparatus' of the kind described and shown in my Patent No. 595,755, of December 21, 1897.

The object of my invention is to provide simple and effective mechanism adapted to the purposes above described.; and the nature of my improvements will be best understood as described in connection with the drawings in which they'are illustrated, reference being now had to the drawings in which my invention is illustrated. Figure l is a side elevation of my machine; Fig. 2, a plan thereof; Fig. 3, a side elevation of the planing-machine proper on an en z larged scale and on the section-line 3 3 of Fig. 4. Fig. 4 is an end View takeny as on the section-line 4 4 of Fig. 3. Fig. 5 is a plan View of the workholding bed and clamping-ring, Fig. 6 is a perspective view of an annular ring such as my machine is especially adapted to plane.

A A, Figs. 1 and 2, indicate bearings for the driving-shaft B, upon which, as shown, is secured the belt-wheel B and the cranks B2 and BB, the crank BE being formed with a slot h3, as indicated in Fig. l.

C is the frame or bed of the planingemachine proper, at each end of which are secured upwardly-extending standards C C', having at their upper ends bearings C2 for the ends of the shaft I. The bed-plate C has formed in its opposite ends bearings C3 C3 and is cut away between such bearings to form the slide Cf1 C4 (best shown in Fig. 3) and the screwway C5.

D D are plates bolted on the frame over-A hanging the slideway C4.

E is a work-holding 4table formed with flanges E E', which rest on the slideway CJL and beneath the plates D, as shown. From the bottom of the table E extendsa screwthreaded lug E2, and in line therewith a re- -cess E3 is formed alongvthe bottom of the table. From the top of the table extends a projection E4, having the conformation of the inside of the ring to be planed and the top of which (indicated at'e) is concavely curved, so as toV clear the cutting-tool which works over the bed-plate or table.

F F 'are ring-segments provided with pro' jecting ears F F, by means of which such segments are clamped around the ring. When in place on the table, these ring-segments are formed with horizontally-projecting flanges F2, by means of which they are bolted to the table, f2 indicating the bolts, and it will be obvious that the ring clampedbetween these segments and secured by them to the table will be held absolutely immovable thereon.

G is a shaft having bearings in the frame at C3 C3 and formed with a feed-screw G on its central part, which screws into the threaded lug or projection E2. It will be obvious that by rotating the shaft G the table E will be fe'd forward or'backward.

G2 is a ratchetewheel secured on the end of Y the shaft G, and G3 a crank-arm by which the- I h', which holds the pawl in contact with the ratchet-wheel.

From the end of the lever H a link HSe leads to the crankearm B?, connecting with said arm by a 'pin adjustablein the slot d3 and the adjustment of which regulatesthe amount of feed-f-that is, the length vof the stroke of the lever H--which by means ofthe pawl and ratchet above described rotates the shaft G.

I is a shaft, the ends I I of which have their bearings at C2 C2 in theupright stand'- ards C. Secured to the shaft I is the arm I2, which has at its lower end a tool-holding re; cess Is and threaded hubs or bosses I4r 15e The arm I2 is pivotally connected at i with a link or connecting-rod I6, which in turnis connected tothe crank-arm B2, as shown vin Figs. 1 and 2.

J indicates the cutting-tool, held in the re cess 18 by the binding and adjustment screws K. K.- Y

AItwil'l be obvious that; with; eachrevoluen tion of the shaft B the cutting-tool is caused t I cla-ifm asnew, and desire to securewby'Lettersl1.
